GM and Autodesk Advancing Design and Manufacturing

General Motors is working with Autodesk on utilizing advanced design software and 3D printing capabilities to develop parts that are not only lighter than those otherwise developed, but which combine what would otherwise be separate parts, thereby reducing manufacturing complexity.
It’s called “generative design.” Essentially, through the use of advanced AI-based algorithms and cloud computing horsepower they are able to run through hundreds of configurations on the way to finding the best design.
According to Ken Kelzer, GM vice president, Global Vehicle Components and Subsystems, “When we pair the design technology with manufacturing advancements such as 3D printing, our approach to vehicle development is completely transformed and is fundamentally different to co-crate with the computer in ways we simply couldn’t have managed before.”
To get to this proof-of-concept 3D-printed seat bracket, GM engineers, working with Autodesk generative design software, quickly assessed more than 150 different approaches to the design before coming up with this.
As an example, they developed a 3D printed seat bracket that combines what would otherwise be eight different components into a single structure, a structure that is 40 percent lighter and 20 percent stronger than one made with conventional processes.
Explains Scott Reese, Autodesk senior vice president for Manufacturing and Construction Products, “Generative technologies fundamentally change how engineering work is done because the manufacturing process is built into design options from the start. GM engineers will be able to explore hundreds of ready-to-be-manufactured, high-performance design options faster than they were able to validate a single design the old way.”
There is a lot of discussion about how 3D printing/rapid prototyping/additive manufacturing is revolutionizing manufacturing, including automotive manufacturing.
Topology optimization cuts part development time and costs, material consumption, and product weight. And it works with additive, subtractive, and all other types of manufacturing processes, too.
According to the folks at Sculpteo, a 3d printing and engineering services company based outside of Paris, they built what they describe as “the first ever fully functional bike created using digital manufacturing.” To prove that this is a real bike, not a booth exhibit, the two designers of the bike, Alexandre d’Orsetti and Piotr Widelka, rode it from Las Vegas, where it had been on display at CES, to San Francisco, where Sculpteo has a facility.
